4 Claims.

This invention relates to loose leaf record books.

An object of the present invention is to provide a loose leaf binder ofthe record book type, the covers of which are hingedly secured to theback member without resorting to the use of metallic hinges.

Another object of the invention is to provide a loose leaf binder of therecord book type with non-metallic cover hinges which are so constructedas to provide a hinge structure which compares favorably with metallichinges both from a structural and use standpoint.

Still another object of the invention is to provide a loose leaf binderof the record book type having the hereinabove characteristics which maybe rapidly and economically manufactured, for the most part, fromnon-critical materials.

Heretofore it has been common practice in the art of manufacturing looseleaf binders of the record book type to hingedly attach the covermembers to the back of a record book by means of metallic hinges, suchas, by way of example, are disclosed in the H. Auburn Patent No.1,891,037, dated December 13, 1932; the E. C. Hazel et al. Patent No.1,925,719 dated September 5, 1933; or the J. Cooper Patent No. 2,067,846dated January 12, 1937. Such metallic hinges comprised, broadlyspeaking, a pair of wing members one of which was secured to or madeintegral with a metallic back member and the other wing member of whichwas secured to a cover by means of riveting, or the like, as disclosedin the hereinabove enumerated patents.

The object of the present invention is to pro vide a loose leaf binderof the record book type in which the number of metallic parts has beenreduced to a minimum without sacrificing the desirable structuralfeatures which should be embodied in such devices. Devices embodyingteachings of the instant invention permit sixty percent of the metalwhich was formerly used in similar binders to be saved, with a fiftypercent reduction in the weight of the finished product.

These and other objects are attained by the means described herein anddisclosed in the accompanying drawing in which:

Fig. 1 is an end view of a. loose leaf binder of the record book typeembodying the teachings of the present invention.

Fig. 2 is a sectional view of the record book of Fig. 1 with the coversin an open or extended position.

Fig. 3 is a perspective view of a loose leaf binder of the record booktype with-the various component parts thereof in a separated orspaced-apart relationship for clarity of detail and understanding.

The binder comprises, generally speaking, a back III, a pair of covermembers I I and a pintle rod assembly I2 which comprises a pair ofpintle" rod housings I3 secured in spaced parallelism along the oppositeedges of attachment plates I4.

With particular reference to Fig. 2, it will be observed that back IIJcomprises a wooden form I5 having an inner face 40 and an outer face 4|.If desired, form I5 may be fabricated from any other non-metallicmaterial such as, by way of example, plastic, or the like, having dueregard for size and shape. A plurality of bolt holes I6 may be drilledor otherwise provided through member l5, said holes being disposed alongthe longitudinal axis of said member. Preferably, the outer end of eachbolt hole I6 terminates in a nut receiving recess I 1. Member I5 may becovered with a canvas, denoted generally by the numeral I8, and thecanvas may then be covered with leather, or other suitable finishingmaterial denoted generally by the numeral I9. The ends of the coveringmaterial may be turned inwardly over inner face 40 of the back form I5to which it may be secured by means of gluing, tacking, or the like. Itwill. be understood that before applying the canvas and leathercoverings to back form I 5, a nut 20 will be inserted in each ofrecesses II, whereby said nuts will be concealed from view by reason ofthe canvas and leather covers.

Cover members II may likewise be fabricated from suitably shaped coremembers or cover boards 2| which may be made from wood, cardboard, orother suitable material made up to the desired size and beveled. A heavypiece of canvas 22 may then be glued directly to the inner face ofboards 2I with a free edge of canvas projecting forwardly from inneredge 23 of cover board 2|. As disclosed in Fig. 3, the width of canvas22 may be of a dimension considerably less than the width of cover board2|, said canvas extending forwardly from free edge 23 two or threeinches.

The outer face of the cover member may then be provided with a suitablefinish covering 24 of leather, or the like, which may be glued directlyto the cover board. As disclosed in Fig. 3, it will be observed that theends of the finish covering 24 may be turned forwardly over the ends ofthe cover boards, and so as to overlie the ends of canvas strips 22,thereby providing a neat durable finishedouter edge 42.

After the covers have been lined, gold-tooled, etc., the outwardlyprojecting free ends of the pieces of canvas 22 and finish covering 24are laid over and secured to the inner face of back by means of aplurality of tacks denoted generally by the numerals 25. Preferably thetacks are disposed in staggered relationship as disclosed in Fig. 3.

The pintle rod assembly l2 may then be secured to the back member bymeans of bolts which may be inserted through bolt Openings 3| providedin attachment plates [4, and which bolt openings are adapted foralignment with their respective bolt holes l6 provided in back member I5. It will be observed that attachment plates is will overlie theheads'of those tacks over which they extend thereby effectivelyprecluding accidental and/or unintentional loosening or withdrawal ofsaid tacks from back member l5. In order to further secure the pintlerod assembly to the back member, a plurality of screws 32 (see Fig. 2)may be inserted through suitable openings 33 provided in lower attach-Inent flange or leg 34 of each pintle housing It and attachment platesl4, said screws extending through canvas 58, finish covering 59 andprojecting into back member 15.

In the preferred embodiment of the invention, attachment plates i l maybe relatively narrow, as disclosed in Fig. 3, in which event it isdesirable to provide filler pieces 40 between adjacent attachment platesfor the purpose of providing a fiat plane surface between the spacedpintle housings It. If desired, such filler ieces may be fabricated fromcardboard, or the like. It is preferable that the outermost row of tacks25 be aligned so as to be disposed beneath attachment leg at of thepintle housing It whereby such tacks will at all times be positivelyheld in place. If desired, those portions of canvas l8 and leather 19which are tacked to back member l5 may be likewise glued thereto,however for strength and durability it is highly desirable that at leastone row of tacks be utilized for the purpose of securing the canvas andleather strips to the back member.

It will be observed that covers H are thus hingedly secured to theopposite edges of back ll! by means of a hinge comprising a thickness ofcanvas and a thickness of finish covering. Tests have indicated thatsuch a hinge while considerably lighter in weight than a metallic hinge,is nevertheless quite as satisfactory as a metallic hingev Such testslikewise indicate that the present hinge will withstand the usual typeof service and abuse to which loose leaf binders of the record book typeare subjected to for a period of many years, wherefore it is seen thatthe life of the record book has not been shortened by reason of havingdispensed with metallic hinges.

It should be understood that the present invention is not directed to,nor concerned with any particular type of means for actuating the pintlebars i which carry pintles 43. Such means may be fully automatic, semiautomatic or manual, depending upon the particular usage to which thebinder will be put.
